FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 374,490, dated December 6, 1887.

Application filed April 18. 1887. Serial No. 235,216. (No model.)

To all whomI it may concern.:

Be it known that I, ORVILLE M. Monsn, of the city of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Flour-Bolts, of

which the following is a specification. Thisinvention relates to that class of separating-machines which are provided with in clined or shaking screens, and has the object :o to produce a machine in which the desired separation is effected upon a smaller screensurface and more uniformly and expeditiously than heretofore.

My invention is especially designed for use in flour-bolts and other separating-machines, which are employed in the reduction of grain or the manufacture of flour; but it may be employed in various other separati11g-machines.

My invention consists, principally, in the 2o combination, with the screen, of a cleaner of peculiar construction, as will be hereinafter fully described, and pointed out in the claims. In the accompanying drawings, consisting ,of two sheets, Figure l is a longitudinal sec- 2 5 tional elevation of a separator provided with my improvements. Fig. 2 is a front elevation thereof, partly in section. Fig. 3 is a crosssection in line x x, Fig. 1. Fig 4. is a fragmentary front elevation of the cleaner. Figs. 3o 5 and 6 are sections of the same, respectively in lines x x and y y, Fig. 4. Fig. 7 is a longitudinal section of a screen provided with my improved cleaners on both sides. Fig. 8 is a perspective view showing a modified construction of my improved cleaner. Fig. 9 is a fragmentary front elevation of another modified construction of the cleaner. Fig. 10 is a crosssection inline x x, Fig. 9. Fig. 1l is a sectional view showing a modified application of the cleaner.

Like letters of reference refer to like parts in the several figures.

A represents the stationary case of the separator; B, the main inclined screen, arranged in the same and receiving a shaking or jarring motion in any suitable manner. As shown in the drawings, the screen B is actuated by a flexible connecting-rod, b, from an eccentric, b, and is provided with corrugated shoes c, 5o which run on supporting-rollers C, attached to the case A, whereby the screen is at the same time moved back and forth and jarred.

D represents the feed-trough secured to the head of the screen-frame, and E represents the feed-box,a1ranged transversely on the case 55 A above the head of the trough D, and provided in its bottom with a slot, e, through which the material to be separated is discharged iuto the trough D, from which latter `it flows upon the head of the screen. 6:

f is the feed-spout, and F a screw-conveyer arranged in the feed-box E, for distributing the material throughout the length of the feedbox.

G represents the cleaner applied to the upper surface of the screen B, and provided with curved or bent wires g, which rest upon the screen and produce vibrations of the screensurface, whereby particles which tend to lodge in the meshes of the same are dislodged. These 7o wires also distribute the material over the screen-surface, whereby all parts of the latter are called into action in effecting the separation, thereby increasing the separating capacity of the screen materially. The cleanerwires further operate as obstructions, whereby the downward passage of the material is re tarded, thereby preventing the material from increasing its speed as it Hows over the screen, which would result Vin animperfect separation 8o ou the lower portion of the screen. The wires of the cleaner also cause the material to turn over or change its position frequently as it flows over the screen, thereby bringing all parts of the material in contact with the screen- 8 5 surface.

' As shown in Figs. l and 2, the wires g of the cleaner are secured to a frame, g', which is nearly as large as the screen, and which receives a reciprocating or other suitable motion 9o exceeding somewhat the size of the mesh of the cleaner, so that the wires are brought in contact with all parts of the screensurface. I prefer to bend the wires f/ spirally, as represented in Figs. i, 5, and 6,ai1d-to interlock 95 every two adjacent wires by twisting one into the other, so that the system of cleaning wires forms a net of interlocked spiral wires, as represented in Figs. 2 and 4. This net is very flexible and accommodates itself easily to the roo surface of the screen; but if a certain degree of stiffness is required in the cleaner it is readily obtained by inserting stiffening-bars hinto the wires. The spirally-twisted wires rest upon the bolting-cloth of the screen with only a very small part of each of their depressed portions, whereby the wear of the boltingcloth is reduced to a minimum and the cloth is enabled to vibrate freely, as it is not held down by considerable lengths of wire resting on the cloth. The spiral wires are also more ieXible than straight wires and follow the undnlations of the screen-surface more closely, while they cause the material to turn over more frequently in passing over the screen.

The cleaner-frame g may be moved laterally over the screen by levers I, which are pivoted t-o the case A above the screen and engage with the upper cross-bar of the frame g'. The levers I are connected to a transverse rod, z', which receives motion from a lever, j, and cam J. The side bars of the cleanerAframe are provided with guide-pins r, which slide in openings in the side pieces of the case A, whereby the cleaner is supported above the L represents a secondary screen, which is arranged below the main screen B and receives the material which has passed through the upper portion of the main screen. This lower screen is provided on its upper surface with a cleaner, G', similar in construction to the cleaner G. The lower cleaner, G, is actuated by eccentrics m and reds m', and the screen L is jarred by a cam, n, engaging against a nose, n', on the screen-frame.

If desired, each screen can be provided with an upper cleaner, G, and a lower cleaner, G2, as represented in Fig. 7.

In the modified construction represented in Fig. 8 the cleaner is formed by transverse wires o, which are bent in U form, and longitudinal wires o', which are interlocked with the raised ble to confine the material on the same by an apron, It, of cotton cloth, canvas, or other suitable material, placed upon the cleaner, as represented in Fig. 7. This prevents particles from jumping above the cleaner and passing over a considerable portion of the screen at one bound.

I claim as my invention- 1. The combination, with the inclined shaking screen, of a cleaner arranged above the screen and composed of a frame having its bars connected by bent wires formed with-alternate depressions and elevations, which wires rest upon the screen, whereby the material is distributed and the flow of the material over the screen is retarded, substantially as set forth.

.2. The combination, with the separatingscreen, of a cleaner arranged upon the screen and composed of a frame having its bars connected'by bent wires formed with alternate depressions and elevati'ons,which wires rest upon the screen, and actuating mechanism whereby the cleaner is moved over the screen, substantially as set forth.

3. The combination, with the inclined shaking screen, of a flexible net composed of interlocked wires resting upon the screen, whereby the iiow of the material over the screen is equalized and retarded, substantially as set forth.

4c. The combination, with the inclined shaking screen, of a cleaner resting upon the screen and composed of spirally-twisted wires, substantially as set forth.

5. The combination, with .the inclined shaking screen, of a cleaner resting upon the screen and composed of spirally-twisted wires interlocked with each other, substantially as set forth.

6. The combination, with theinclined shaking screen, of a cleaner-frame arranged above the screen and having its bars connected by bent wires constructed with alternate depressions and elevations, and mechanism, substantially as described, whereby the cleaner-frame is moved laterally on the screen, substantially as set forth.

7. In a separating-machine, the combination, with an inclined shaking screen, of a cleaner-frame provided .with bent wires which bear upon the surface of the screen and retard the flow of material over the same, and an apron placed upon the cleaner, whereby the material is confined, substantially as set forth. fitness my hand this 5th day of April, 1887.
